Female-led infanticide in wild chimpanzees

of chimpanzee screams, the researchers directly observed one infanticide, and found strong circumstantial evidence for two others. Evidence suggested that in two of the cases, the killings were perpetrated by groups of resident females against "stran...

Bisexual fruit flies show new role for neurochemical

silly, but these behavioral changes are important evidence that ambient extracellular glutamate and xCT transport proteins play important, unsuspected roles in brain function," Featherstone said. "We think we'll be able to learn a lot about perceptio...
Research finds music training 'tunes' human auditory system
...heir attention focused on the movie and though the sounds
had no linguistic or musical meaning for them, we found our musically trained subjects were far better at tracking the three different tones than the non-musicians," says Wong, director of Northwestern’s Speech Research Laboratory and assistant profe...
Neural bottleneck found that thwarts multi-tasking

are coming from. "Clearly, our acoustical understanding often improves if we can see the lips of the speaker—for example at a crowded cocktail party," he says. "However, currently it is not clear whether and how audio-visual interactions are speciali...
Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply
...en Peterson sampled bay scallops in North Carolina sounds
in late summer before and after the cownose rays passed through, he found that most scallops survived the ray predation, allowing the scallop population to support a fishery and still replenish itself each year. In contrast, sampling by Peterson and ...

Sensory feedback during speech: The brain attunes to more than just sound
